Question

Why isn't Hess's law helpful to calculate the heat of reaction involved in converting a diamond to graphite?

Answer 1

Answer:

The free energy difference between graphite and diamond is rather small; graphite is a tad more thermodynamically stable. The activation energy required for the conversion would be monstrously large!

Thanks :)

Answer 2

In a sugar, the D or L designation refers to the configuration of the chiral carbon farthest from the aldehyde or keto group. This is C-5 in glucose. ... They have the same name, for example, D-glucose and L-glucose
